One thing's for sure: over the past several months, there's been no shortage of zombie games. Whether you're going toe-to-toe with the undead in Dead Trigger, using them as motivation in Zombies, Run!, or showing off your green thumb in Plants vs. Zombies, the walking dead are everywhere. It's like a zombie apocalypse without, you know, the apocalypse.

If you're looking for an apocalyptic nightmare that may hit closer to home, however, a new game called Global Outbreak may fit the bill.
